Pure Resonance Audio RMA240BT 240W Bluetooth Rack Mixer Amplifier

The Pure Resonance Audio RMA240BT is the kind of amp you choose when you want a clean, professional setup that just works, for music, paging, and announcements. It combines a commercial rack mount mixer amplifier with 240W of Class D power, plus Bluetooth, so you can run day-to-day background music without adding extra boxes.

What makes it especially practical is the output flexibility. You can run it as a 4 ohm amplifier for traditional low-impedance speaker loads, or build out a 70V speaker system for longer wire runs and multi-speaker installations. That means the RMA240BT can fit a lot of real-world jobs, like a retail floor with consistent music coverage, a school front office that needs clear announcements, or a restaurant that wants simple control with reliable performance.

The 5-channel mixer section gives you room to manage multiple sources, like music playback and paging, without making the rack complicated. And because commercial installs live or die by uptime, Pure Resonance added forced-air cooling to help the amplifier stay stable when it is working hard.

One more feature that matters in public address environments is emergency priority. In plain terms, it is designed to support higher-priority messaging when it matters most, which is exactly what you want in a complete paging and announcement audio system.

If you are searching for phrases like rack mount mixer amplifier with Bluetooth, 70V mixer amp, or commercial paging amplifier, the RMA240BT checks the boxes with a simple, installer-friendly approach.
